A document or application is considered accessible if meets certain technical criteria and can be used by people with disabilities. This includes access by people who are mobility impaired, blind, low vision, deaf, hard of hearing, or who have cognitive impairments. PDF documents and forms, with and without the aid of assistive technology software and devices such as screen readers, screen magnifiers, text-to-speech software, speech recognition software, alternative input devices, Braille embossers, and refreshable Braille displays. One benefit of following these guidelines is that content becomes more usable for all users. For example, the underlying document structure that makes it possible for a screen reader to properly read a PDF out loud also makes it possible for a mobile device to correctly reflow and display the document on a small screen.
Similarly, the preset tab order of an accessible PDF form helps all users—not just users who rely on the keyboard—complete the form more easily. The PDF format is the native file format of the Adobe Acrobat family of products. The goal of this format and these products is to enable users to exchange and view electronic documents easily and reliably, independently of the environment in which they were created. PDF also includes objects, such as annotations and hypertext links, that are not part of the page itself but that are useful for interactive viewing and document interchange. A logical tagged structure tree is used within each document to provide a meaningful reading order for content, as well as a method for defining structural elements role and relationship to page content. Within this tag structure, other properties such as alternative text and replacement text can be provided.
PDF files are created in a variety of ways, from a variety of applications, and for a variety of purposes. Achieving the desired accessibility goals for an individual PDF file requires understanding the nature of the PDF and its intended use. Adobe Acrobat Pro DC provides several tools including the Make Accessible Menu in the Action Wizard mode and the Accessibility Checker to assist authors in evaluating and fixing issues that can impact accessibility. The Adobe Acrobat Pro DC Accessibility Guide: PDF Accessibility Repair Workflow document provides details on how to assess existing PDF files for accessibility. By following these procedures in the recommended order, authors can efficiently proceed through the analysis of a PDF file in a systematic fashion.
